Best time to meet
No shared working hours.
Tokyo and Buenos Aires are too far apart for a working-day overlap. The least-unsociable option is an early-morning call on one side and an evening one on the other — or hand work off asynchronously and let the planet do the waiting.

- There's no comfortable 9-to-5 overlap between Tokyo and Buenos Aires — they sit on opposite sides of the planet's working day. Plan for an early or late call on one side, or hand work off asynchronously.
- Does this account for daylight saving time?
- Yes. We track every clock change in both places, so the abbreviations you see — JST and -03:00 — are the ones actually in effect right now, not a fixed all-year value. When either side changes its clocks, this page updates automatically.
- Why is the date sometimes different on each side?
- When two places are far enough apart, the same moment can fall on different calendar days. That is why some conversions are marked "previous day" or "next day" — it is the same instant in time, read off two clocks that crossed midnight at different points.
